            For custom CoreUI form validation messages, you&#39;ll need to add the
            <code>novalidate</code> boolean property to your <code>&lt;CForm&gt;</code>. This
            disables the browser default feedback tooltips, but still provides access to the form
            validation APIs in JavaScript. Try to submit the form below; our JavaScript will
            intercept the submit button and relay feedback to you. When attempting to submit,
            you&#39;ll see the <code>:invalid</code> and <code>:valid</code> styles applied to your
            form controls.

            Custom feedback styles apply custom colors, borders, focus styles, and background icons
            to better communicate feedback.

            We recommend using client-side validation, but in case you require server-side
            validation, you can indicate invalid and valid form fields with <code>invalid</code> and
            <code>valid</code> boolean properties.
          </p>
          <p class="text-body-secondary small">
            For invalid fields, ensure that the invalid feedback/error message is associated with
            the relevant form field using
            <code>aria-describedby</code> (noting that this attribute allows more than one
            <code>id</code> to be referenced, in case the field already points to additional form
            text).

            If your form layout allows it, you can swap the text for the tooltip to display
            validation feedback in a styled tooltip. Be sure to have a parent with
            <code>position: relative</code> on it for tooltip positioning. In the example below, our
            column classes have this already, but your project may require an alternative setup.
